Why is Your Dishwasher Not Draining?

A number of factors can cause your dishwasher not to drain properly. It could be due to a clog, a faulty drain pump, or an issue with the drain hose. By systematically checking each potential problem, you can identify the exact reason behind the drainage issue.

Step 1: Inspect the Drain Filter and Clean If Necessary

Start by checking the dishwasher’s drain filter. Food particles and other debris can block the filter, preventing water from draining.

  1. First, unplug the dishwasher or switch off the breaker to avoid any electrical accidents.
  2. Open the dishwasher door and locate the drain filter. This is typically found at the bottom of the dishwasher.
  3. Consult your dishwasher’s manual if you’re unsure of where the filter is located.
  4. Remove the filter by turning it counterclockwise and lifting it out.
  5. Rinse the filter under running water and use a soft brush to remove any debris.
  6. Once clean, reinsert the filter by placing it back in its housing and turning it clockwise until it is secure.
  7. Plug in your dishwasher or turn the breaker back on and run a cycle to see if this has solved the issue.

Step 2: Check the Drain Hose

If cleaning the filter doesn’t solve the problem, the issue may lie with the drain hose. A kinked or clogged hose can prevent water from draining.

  1. Unplug your dishwasher or switch off the breaker.
  2. Typically, the drain hose is located at the back of the dishwasher. You may need to move your dishwasher away from the wall to access it.
  3. Check the hose for any kinks. If you find any, straighten them out.
  4. If there are no visible kinks, check for clogs. To do this, remove the drain hose from the dishwasher and the sink drain or garbage disposal where it is attached.
  5. Use a long flexible brush to clean out the inside of the hose, or you can run water through it to clear any blockage.
  6. Reattach the hose, ensuring it is secure at both ends.
  7. Plug your dishwasher back in or turn the breaker back on, and run a cycle to check if the issue has been resolved.

Step 3: Test the Drain Pump

If the first two steps haven’t resolved the issue, it’s time to test the drain pump. The pump uses an impeller to force water into the drain hose. If the pump is broken, the dishwasher won’t drain.

  1. Ensure your dishwasher is unplugged or the breaker is off.
  2. Locate the drain pump. The exact location can vary, so consult your dishwasher’s manual if needed.
  3. Inspect the pump for any signs of damage or blockage.
  4. If the pump is damaged, you’ll need to replace it. You may want to consider hiring a professional for this step as it can be more complex.
